Sodium Chloride

| Describe how and when the different types of fire extinguishers, relevant to the given occupation, are used in accordance with legislation and official guidance.QCF641. 3.7 & 3.8

The principle behind the extinguisher is simple: as they are mechanical pressure waves that cause vibrations in the medium in which they travel.

Dry chemical extinguishers put out fire by coating the fuel with a thin layer of dust, separating the fuel from the oxygen in the air. The powder also works to interrupt the chemical reaction of fire, so these extinguishers are extremely effective at putting out fire. It is very effective with a low risk of re-ignition.

Calcium chloride has a consistency of salt, they are white little flake and particles. calcium chloride at room temperature is a solid, it is used for dust control it has a generic formula of

PURPOSE:  to determine which of the 3 ionic compounds (NaCl, LiCl, or NaCH3COO) is most

Clouds to form in the atmosphere have to have water vapor present. This water vapor makes up a cloud. The water vapor in the atmosphere comes from evaporation or deposition. Also the temperature of the air is below the dew point. When the water is fully saturated, it starts to rise and the expansional cooling process begins. During the process of condensation, the aerosol particles act like a nuclei in the atmosphere, which began to grow, creating ice crystals that are big enough to produce a cloud.

If you dissolve a substance such as ordinary table salt (NaCl) in water, the boiling point of the water will increase relative to the boiling point of the pure water. In this assignment, you will dissolve a sample of NaCl in water and then measure the boiling point elevation for the solution.

Salt – the only rock we eat – has made a glittering, often surprising contribution to the history of humankind.

Potassium Chloride is a metal halide salt composed of potassium and chlorine. In its pure state, it is odorless and has a white or colorless vitreous crystal appearance. It is commonly used in fertilizer.

Road salt, or rock salt as it's sometimes referred to, has the same molecular make-up as the salt used in food: sodium chloride. While table salt is purified, ground and combined with additives to prevent it from clumping, road salt is coarser in texture and larger in size. It is primarily made from mining it under the ground, where

Salt uses some basic laws of chemistry to break down accumulation of ice. As you know, salt is an ionic compound, Sodium Chloride. According to intermolecular forces, ionic compounds have the highest melting and boiling rates. Ice’s melting point is at 0 degrees whereas Salt’s is about 800 degrees.

“Salt, A World History,” is an extensive aspect of world history by Earth’s one edible rock - salt. The book begins at the start of recorded history, and highlights humanity’s dependence on salt, up to roughly present day times. It focuses on the effect salt had on, and its contributions to, humankind. The book details how salt affected, economics, religion, science, and culinary practices all over the world.

Intermolecular forces hold molecules together when they are in solid or liquid state. However, water has the ability to dissociate many salts and ionic compounds. This is called dissolving. When NaCl is added to water, it dissociates into the ions; Na+ and Cl- . The positive sodium ions are surrounded by the slightly negatively charged part of water molecules (i.e. oxygen) in the water molecules and the negative chlorine ions are surrounded by the slightly positively charged part of water molecules (i.e. the hydrogen). The kinetic energy of the sodium chloride molecules increase with temperature. This destabilizes the solid state that it is currently in. This increased motion means that the molecules are less able to hold together and as such they dissolve at faster rates and larger amounts.

In light of my previous response I can conclude that salt is formed from the

There are many different brands of aquarium salt available to the hobbyist, and each one has its own following of people that will swear by its use. Any brand available will work since it is very unlikely the inhabitants will be able to tell the difference. However, what is more important than the brand of sea salt is the amount that is added to the water.
